Abstract
A plug for closing box-like bodies, which comprises a head that has a circular perimeter and from which at least two substantially flat stems protrude substantially tangentially, the plug entering, by means of the stems, the box-like body through an opening provided in a wall of the box-like body, each stem having snap-acting elements for quick engagement with a portion for accommodating the box-like body and at least one elastically deformable portion designed to be compressed during insertion.
Description
- The present invention relates to a plug for closing box-like bodies.
- In order to close such bodies, intended particularly but not exclusively to contain electrical or hydraulic devices, exposed screws are often used which mutually associate two walls of the box-like body, at their edges, or fix them directly to internal components of the device.
- Although very widespread, this method for closing the box-like body suffers the drawback of being scarcely practical, since it requires a significant number of fixing screws and therefore an unnecessary extension of the time to be dedicated to opening and closing the device for assembly or for any maintenance interventions.
- Moreover, the presence of numerous screws on the exposed faces of the product often has a scarcely appreciated aesthetic impact.
- Another drawback, in the case of box-like bodies that contain hydraulic devices, is that if such devices are designed with more than one intake or delivery duct, to be selected in use as needed, such box-like bodies can be provided with a plurality of openings, each one at a duct. It is advisable to keep these openings closed when the corresponding ducts are not used.
- The aim of the present invention is to provide a plug for closing a box-like body that allows to engage, in a practical and quick way, the walls to which it is applied.
- Within this aim, an object of the invention is to provide a plug for closing box-like bodies that eliminates the problems of aesthetic impact that can be observed with fixing screws.
- Another object of the invention is to propose a plug which, in addition to allowing easy and quick closure of the box-like body that encloses a hydraulic device, allows to open and close the intake and delivery ducts on the basis of the connections that it is necessary to provide with the hydraulic systems, without having to open the box-like body.
- This aim, as well as these and other objects that will become better apparent hereinafter, are achieved by a plug for closing box-like bodies, characterized in that it comprises a head that has a circular perimeter and from which at least two substantially flat stems protrude substantially tangentially, said plug entering, by means of said stems, said box-like body through an opening provided in a wall of said box-like body, said head engaging, by means of its rim, the rim of said opening and each stem having snap-acting means for quick engagement with a portion for accommodating said box-like body and being provided with at least one elastically deformable portion which has substantially the shape of a leaf spring provided in one piece with the rest of the stem and designed to be compressed during insertion.
- The present invention relates further to the use of the plug to close a box-like body that contains a hydraulic pumping device, said plug being insertable with the stems around a delivery or intake duct of said hydraulic pumping device and said head being closable by means of a closure to be inserted in the mouth of said duct.
- Further characteristics and advantages of the invention will become better apparent from the description of two preferred but not exclusive embodiments of the plug according to the invention, illustrated by way of nonlimiting example in the accompanying drawings, wherein:
-
FIG. 1 is a perspective view of the plug according to the invention in its first embodiment; -
FIG. 2 is a sectional side view of the plug according to the invention, again in the first embodiment; -
FIG. 3 is a view of the insertion of the plug according to the invention, in its second embodiment, through the opening of a wall of a box-like body that contains a hydraulic device; -
FIG. 4 is a view of a portion of a device enclosed in a box-like body, the upper and lower walls of which, relative to the drawings that illustrate it, are each fixed by means of a plug according to the invention; -
FIG. 5 is an enlarged-scale sectional view of the plug according to the invention in its second embodiment, inserted to close a box-like body and with the closure applied to the mouth of a duct of the hydraulic device contained therein. - With reference to the figures, the plug according to the invention, generally designated in its first embodiment by the
reference numeral 10, is preferably made of plastic material and, as shown clearly in particular inFIG. 1 , comprises ahead 11 that has a circular perimeter and from which two substantiallyflat stems 12 protrude substantially tangentially. With these stems, theplug 10 enters the box-like body 13 through anopening 14. Theopening 14 is conveniently also circular and provided in awall 15 of the box-like body 13 to be closed. - The
head 11 engages thewall 15, resting with its rim against the rim of the opening 14 (as shown inFIG. 5 for the second embodiment). - Each one of the two
stems 12 has means 16 for snap-acting quick engagement with aportion 17 for accommodating the box-like body 13, which it enters during the insertion of theplug 10. - In particular, said snap-acting quick engagement means 16 comprise a
tooth 18 for snap connection to theaccommodation portion 17, which has acorresponding insertion seat 19 for thetooth 18. The coupling is clearly visible inFIG. 4 . - Each one of the two
stems 12, being made of plastic material like the rest of theplug 10, is also advantageously provided with at least one elasticallydeformable portion 20, which is shaped substantially like a leaf spring that is provided in one piece with the rest of thestem 12 and is intended to be compressed during the application of theplug 10, or during the insertion of saidstem 12 in theaccommodation portion 17, until thetooth 18 enters theinsertion seat 19. - As clearly visible from the perspective views, the two
stems 12 are, as mentioned, substantially flat and have at one end the elasticallydeformable portion 20 and, at the opposite end, thetooth 18. - The elastically
deformable portion 20 is extended substantially along the entire length of thestem 12 and the part that is subject to deformation is the one that is slightly curved outwardly. - The
tooth 18 protrudes proximate to the end of thestem 12 and is defined by acontoured recess 21 for the disengagement of thetooth 18 by way of the lateral insertion of tools such as a flat screwdriver and the like. - The
insertion seat 19 must be conveniently open on one side to allow the exit of thetooth 18 following a rotation imparted by the screwdriver. - The two stems 12 face each other and are diametrically mutually opposite with the
tooth 18 of one of them substantially opposite the elasticallydeformable portion 20 of the other. - As mentioned, the
head 11 has a circular rim and, more particularly, has a substantially annular shape with a largerannular portion 22 and a smallerannular portion 23, which creates with the preceding portion aresting step 24 for thehead 11, which associates with abutment with the seat of the opening 14 (thestep 24 is shown inFIG. 2 ). Thestems 12 protrude from diametrically opposite regions of the smallerannular portion 23. - The two
stems 12 can be inserted in asingle accommodation portion 17 that has twocorresponding insertion seats 19 for the twoteeth 18 or can be inserted each in anaccommodation portion 17, as shown for the second embodiment. - Each
stem 12 also advantageously has arecess 25, which, by protruding from its end inwardly, on the rear of the elasticallydeformable portion 20, increases the limit of elastic deformation of thestem 12. - As an alternative, in another embodiment that is not described here, the plug can have a disk-like head in order to close completely the opening 14.
- In its second embodiment, the plug is generally designated by the
reference numeral 110. - Like the preceding one, it comprises a
head 111 having a circular perimeter from which twostems 112 protrude substantially tangentially; by means of said stems, theplug 110 enters the box-like body 13 in the manner already described. - In this embodiment also, each
stem 112 has means 116 for snap-acting quick engagement with anaccommodation portion 17 of the box-like body 13, which comprise atooth 118 for snap connection to theaccommodation portion 17, which has acorresponding insertion seat 19 for thetooth 118. In particular, thetooth 118, as in the first embodiment, protrudes at the end of saidstem 112 and is defined by acontoured recess 121 for the release of thetooth 118 from theinsertion seat 19. - Again like for the
plug 10, eachstem 112 is substantially flat and is provided with an elasticallydeformable portion 120 on one of its sides, while on the opposite side there is thetooth 118. In particular, the elasticallydeformable portion 120 is shaped like a leaf spring that is provided in one piece with the rest of thestem 112 and is intended to be compressed when thestem 112 is inserted in theaccommodation portion 17. - The two
stems 112 face each other and are diametrically mutually opposite, with thetooth 118 of one of them substantially opposite the elasticallydeformable portion 120 of the other. - As occurs for the
plug 10, thehead 111 has a substantially annular shape, with a largerannular portion 122 and a smallerannular portion 123 which creates with the preceding one aresting step 124 for thehead 111, which is associated with abutment with the seat of theopening 14. - The two
stems 112 protrude from diametrically opposite regions of the smallerannular portion 123. - Moreover, the
stem 112 has arecess 125 which, by extending from its end inwardly, on the rear of the elasticallydeformable portion 120, increases the limit of elastic deformation of thestem 112. - Differently from the preceding one, in this embodiment the
plug 110 is also provided with acircular closure 126 whose dimensions are compatible with the part of thehead 111 that is surrounded by theannular portions - The
plug 110 can be used advantageously to close a box-like body 13 that contains a hydraulic pumping device, as shown inFIGS. 3 to 5 , and can be inserted with the twostems 112 around a delivery orintake duct 27 of the device. The twostems 112 each also enter acorresponding accommodation portion 17 on opposite sides of theduct 27. Thehead 111 can be closed, as shown in the exploded view ofFIG. 3 and inFIG. 5 , by means of theclosure 126, to be inserted with itsstem 128 in the mouth of theduct 27. - However, the
closure 126 can also be used as esthetic covering of theopening 14. - Use of the plug according to the invention is as follows and is described only for the second embodiment, since it is similar for the first one except in the insertion of the
closure 126. - The
plug 110, described here in the application to a box-like body 13 that contains a hydraulic pumping device, is applied onopposite walls 15 of the box-like body 13, at least one for each wall, inserting it with thestems 112 through theopenings 14 and then in theaccommodation portions 17 on opposite sides of theduct 27. During the insertion of eachstem 112 in theaccommodation portion 17, the elasticallydeformable portion 120 is compressed, reducing temporarily the overall width of thestem 112, until thetooth 118 enters with a snap action theinsertion seat 19. At this point the elasticallydeformable portion 120 returns completely or partially to its original shape, extending against the wall of theaccommodation portion 17. - The
duct 27 is then closed, inserting theclosure 126 with itsstem 128 in the mouth of theduct 27, optionally screwing it in if the parts are threaded. In this manner it is possible to keep closed the connections of the device that are not used and optionally also open them quickly and easily when necessary without opening the box-like body and removing theentire plug 110 but only theclosure 126. - Other two opposite walls of the box-
like body 13 can be closed traditionally around the device by way of mechanical fixing means such as screws. - If it is necessary to open the box-
like body 13, it is sufficient to remove theplug 126 and one of the other two opposite walls, from the side of which it is easy to access theplug 110 by means of a screwdriver to be inserted in therecess 121, in order to impart a rotation to the plug 110 (also causing a compression of the elastically deformable portion 120), until thetooth 118 exits from theinsertion seat 19. - In practice it has been found that the invention achieves the intended aim and objects, by providing a plug which allows, in the closure of a box-like body, to engage in a practical and quick way the walls to which it is applied, without using screws and thus reducing the total number thereof to be used to close the entire box-like body.
- Another advantage of the invention is that it obtains the engagement of some parts of the box-like body with a better aesthetic impact than that obtainable by using fixing screws.
- A further advantage of the invention is that it can be used, particularly in its second embodiment, not only for the quick engagement and disengagement of the walls of the box-like body but also to ensure easy and quick closure and opening of ducts of a hydraulic device, in order to modify the delivery and intake configurations without having to open the box-like body.
- The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims; all the details may further be replaced with other technically equivalent elements.
- In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to requirements and to the state of the art.
